For several years, together with various Austrian publishers of scientific journals in biology and earth sciences, there has been an attempt to make publications in the form of citations and PDF documents available. More than 400,000 pages already exist and another 200,000 will follow in 2009. The PDF documents are completely OCRed, or are produced directly from digital layouts, so their content can be copied to a text editor. [Information of the supplier, translated]A large number of the articles can be freely downloaded as PDFs (such as those from the journals "Annalen des Naturhistorischen Museums in Wien" and "Linzer Biologische Beiträge"). Other articles and monographs, especially those recently-published, are available to download as a PDF for a fee. Finally, some articles, particularly journals that are not published by the Upper Austrian State Museums, are not yet available in a digitised format.
